High Pressure · PRV Install & Repair · Sonoma County
Pressure reducing valve service — protect your home from high water pressure.
Too much water pressure quietly wears out your faucets, water heater, and pipes — and can void appliance warranties. A pressure reducing valve (PRV) brings incoming pressure down to a safe range. We install, test, and replace PRVs across Sonoma County.

Good to know
Pressure & PRV questions, answered
What pressure should my house be at?
Most homes should sit around 50–70 psi. Above about 80 psi, code requires a pressure reducing valve to protect your plumbing.
How do I know if my pressure is too high?
Banging pipes, fixtures wearing out fast, or a leaking water-heater relief valve are common signs. We confirm it with a gauge.
Do I really need a PRV?
If your incoming pressure is above 80 psi, or you don’t have a working regulator, yes. We test first and tell you straight.
Can high pressure damage my water heater?
Yes — it pushes past the relief valve and stresses your water heater tank. A PRV, often with an expansion tank, protects it.
Banging pipes or pressure too strong? Let’s dial it in.
